 I installed the extension (based on commit `7989810`) in Firefox 67.0.2.
 The snowflake icon shows up in my toolbar but it keeps saying "Offline."

 In the browser console, I see the following:

 I could also install the extension in both Chromium and Google Chrome but
 my icon says "Offline" there as well.
